A low-cost inertial navigation system (INS) and global satellite (GNSS) fusion position estimator is affected by accuracy limitations multiple noises, leading to significant errors in positioning estimation. This paper proposes a new algorithm, SSA-ESKF, which combines singular spectrum analysis (SSA) an error-state Kalman filter (ESKF). The measurement unit (IMU) GNSS data obtained from the re...

This paper shows how two different publicly available epidemiological modelling packages (namely the Spectrum AIDS Impact Model and the ASSA 2003 model) predict very different impacts of rolling out highly active antiretroviral treatment (HAART) on new HIV infections. Using South Africa as a case study, it shows that ASSA 2003 predicts a significant drop in new HIV infections as HAART is rolled...

Inputs to mathematical models can be very uncertain because of incomplete knowledge. These input uncertainties propagate to output uncertainties, and an estimation of these output uncertainties, and of the importance of the individual inputs to these output uncertainties, would be desirable. These estimates can be calculated via Uncertainty Analysis (UA) and Sensitivity Analysis (SA) respective...

Seventeen daucane sesquiterpenoid esters, including a new one (4), were isolated from the root of Ferula hermonis Boiss. The structures of the isolated compounds were elucidated on the basis of spectroscopic evidence and correlated with known compounds. The relative stereochemistry of the new compound was determined using 2D NOESY and the most stable and the lowest energy conformation was deter...

Effect of hexane extract of Ferula jaeschkeana has been studied on the histological and biochemical constituents of the uterus of ovariectomized rats. Its administration caused remarkable increase in the height of luminal epithelium and the number of uterine glands. Its per se treatment also caused significant increase in the glycogen and protein contents and the activity of acid and alkaline p...
